| 20100015428 | METHOD OF FABRICATING A THERMOSTRUCTURAL COMPOSITE MATERIAL PART, AND A PART OBTAINED THEREBY - The method comprises: | 01-21-2010 |
| 20100092281 | TURBINE RING ASSEMBLY FOR GAS TURBINE - A turbine ring assembly for a gas turbine comprises a one-piece split ring ( | 04-15-2010 |
| 20100111678 | TURBINE RING ASSEMBLY FOR GAS TURBINE - A turbine ring assembly for a gas turbine, the assembly comprising a complete ring ( | 05-06-2010 |
| 20100144227 | REINFORCING FIBROUS STRUCTURE FOR A COMPOSITE MATERIAL AND A PART CONTAINING SAID STRUCTURE - A woven fibrous structure embodied in one piece, used for producing a composite material part and comprising an internal part or a core ( | 06-10-2010 |
| 20110200748 | METHOD FOR PRODUCING PARTS MADE OF A THERMOSTRUCTURAL COMPOSITE MATERIAL - A method of fabricating a thermostructural composite material part includes making a fiber preform formed of yarns or tows and impregnated by a consolidating composition containing a carbon- or ceramic-precursor, transforming the carbon- or ceramic-precursor by pyrolysis, and then densifying the preform by chemical vapor infiltration. A consolidating composition is used that additionally contains refractory solid fillers in the powder form presenting mean grain size less than 200 nanometers and leaving, after pyrolysis, a consolidated solid phase in which the carbon or the ceramic derived from the precursor occupies a volume representing 3% to 10% of the apparent volume of the preform, and the solid fillers occupy a volume representing 0.5% to 5% of the apparent volume of the preform. | 08-18-2011 |
| 20110268577 | METHOD FOR SMOOTHING THE SURFACE OF A PART MADE FROM A CMC MATERIAL - A method of smoothing the surface of a ceramic matrix composite part presenting a surface that is undulating and rough. The method includes forming a ceramic coating on the surface of the part, the coating being made by applying a liquid composition on the surface of the part, the composition containing a ceramic-precursor polymer and a factory solid filler, curing the polymer, and transforming the cured polymer into ceramic by heat treatment. The method further includes impregnating the ceramic coating with a liquid metallic composition. | 11-03-2011 |
| 20110277869 | PRODUCTION OF A FIBROUS STRUCTURE WITH VARIABLE THICKNESS BY 3D WEAVING - A method of making a fiber structure by multilayer three-dimensional weaving, the fiber structure having a thickness in a direction perpendicular to the warp and weft directions that varies along the warp direction while conserving the same number of warp yarns that are woven at all points of the fiber structure along the warp direction, wherein during a transition in the warp direction from a first portion of the fiber texture to a second portion of the fiber texture having a thickness that is greater than the thickness of the first portion, the number of warp planes is decreased and the number of layers of warp yarns is increased without changing the number of warp yarns, by constituting at least one warp plane in the second portion with warp yarns taken from at least two different warp planes in the first portion. | 11-17-2011 |
